Non-contact profilometry and reverse engineering with LASER scanner

laser scanner for profile measurement of gears and gears

Contact and non-contact profilometry is a measurement technique used to reconstruct the geometry of an object. Traditionally, contact profilometry has used a rod with a top-mounted force/position sensor to measure changes in the surface of the object. However, the use of laser scanners is becoming increasingly popular for dimensional analysis of object geometry.

This technique uses a laser beam projected onto the object to be measured and allows the profile to be reconstructed quickly and accurately.

Laser scanning systems have been used to generate three-dimensional models of objects and the technology is becoming more common in digital reconstruction. A laser scanner-based system is capable of acquiring detailed information on objects by extending the limits of traditional techniques such as contact profilometry.

The surveying process can be automated and offers accurate results even if the object to be measured is complex and awkward to handle manually.

The use of laser scanners in reverse engineering offers great advantages over the use of conventional tools, such as the possibility of reconstructing complex shapes in addition to the regular ones, such as holes and slots, but also irregular surfaces such as curves and surfaces aesthetics; consequently there is less need to do without some complex geometric functions that would take a very long time to calculate using traditional mathematical methods.

Digital radius and diameter gauge DIACHECK-CT series

The DIACHECK-CT series digital radius and diameter gauge allows direct and instantaneous reading of internal or external radii or diameters in a range between 100 and 10000 mm.

Il High precision digital radius and diameter gauge of the DIACHECK-CT series is designed to measure the radius of cylindrical objects such as pipes, profiles and calenders quickly and accurately.

This measuring instrument allows the measurement of the radius of curvature or, of the internal or external diameter of a certain part using the method of measuring the circumference based on three points.

Technical features

This radius gauge allows direct and instantaneous reading of inside or outside radius values ​​for a wide range of curves, profiles, diameters and cylindrical objects.

  • Comfort: there is no need to cut out templates to find out the radius of a curve, nor to remove the piece from the machine to measure it and not even to extract the part from its installation location (for example underground pipes, installed tanks, positioned and fixed calenders)

  • Ease of use: it's easy to use and the measurement process is lightning fast. Simply place the gauge inside or outside the curve to automatically obtain the value of the radius of curvature or the diameter of the object.

  • Multi-material: the gauge is suitable for any type of solid material such as steel, wood or plastic materials.

  • High precision: the margin of error on the radius is only 0,1 mm (the measurement accuracy depends on the superficial quality of the solid to be measured and it is necessary to work on a surface without depressions or with high surface roughness to obtain maximum precision).

  • Field of application: this radius gauge is supplied with different measuring arcs and with different angles of support. The use of the various arcs offers a measurement range between 100 and 10000 mm.

Innovative and versatile

  • Battery Powered LCD Digital Display: comfortable reading of the measured value with the possibility of transferring the measured value to a acquisition system based on Bluetooth interface.

  • Practical: it is small and light and can be easily used for different measurements by simply changing the measuring head.

  • Transport: An aluminum case with internal foam protection is available to store and protect the meter when not in use. Convenient to carry and shock resistant.

  • Two units of measurement: you can choose whether to measure in millimeters or inches just press the unit conversion button.

  • Ideal for large radii: the measuring tool can measure radii up to 10 meters with the highest precision.

RIMAS - Robotic system for inspection, measurement and assembly of mechanical parts

Robotized system for the automatic inspection of mechanical parts in the production line

Used forassembly of mechanical parts and for the non-destructive quality control.

Wide range of measures and usable technologies (cameras, laser scanners, eddy current, torque cells, dynamometers, laser micrometers, laser marking)

High customization and integration into the production line or existing production flow.

RODER SRL presents RIMAS, the new robotic cell for inspection, measurement, assembly of mechanical parts and non-destructive quality control.

The production island RHYMES ( Robotic Inspection Measurement Assembly System ) allows you to manage in an easy and intuitive way many control and assembly phases typical of the industrial sector:

  • Optical inspection of mechanical parts in the production line (presence of parts / absence of parts / color of components / correct arrangement of parts)
  • Measurement of mechanical and geometric characteristics (heights, diameters, flatness, depths, oscillations, locations)
  • Measurement of integrity characteristics (crack control, magnetic material composition control, visual inspection and defect control)
  • Assembly of mechanical parts
  • Force control and couple
  • Component marking with LASER technology, inkjet, percussion
  • dosage of fluids, glues and resins
  • Profile check with 3D scanners and contact measurement systems

Verification island that allows the non-destructive control of mechanical parts
directly on the production line. It is characterized by an autonomous platform which
integrates an automatic manipulator capable of picking up the piece directly from the line
of production (both on oriented pallets and on sliding belt with recognition
automatic orientation of the piece). The manipulator carries the part to be checked
in the control area where there are one or more measuring instruments (durometers,
profilometers, roughness meters, eddy-current probes, multi-level instruments, roundness meters or any other
other automatic measuring instrument). After checking the manipulator
provides to bring the detail directly into the production flow of the line if the result is
positive. In case of non-compliance, the system takes the part off line for the
subsequent analysis and, if necessary, adjust the parameters
production or the controlled stop of the production process.
